One of our tiniest birds, the Golden-crowned Kinglet is remarkable in its ability to survive in cold climates. Nesting in northern forest, wintering throughout much of the continent, it is usually in dense conifers which undoubtedly help provide shelter from the cold. This choice of habitat also makes the Golden-crown hard to see, but it may be detected by its high thin callnotes, and then glimpsed as it flits about high in the spruce trees.
